The fight “required several players” to separate Cooper and Williams. It ended with quarterback Michael Vick holding back Williams as he continued to shout at Cooper.

The incident comes just five weeks after a video surfaced on the Internet of Cooper using an offensive racial insult. Cooper was fined, apologized to his teammates and took a brief leave of absence to seek counseling.

“Any time there’s something extra on the field with Riley and another teammate or an opponent, that’s the first thing that’s going to come up — especially if the guy’s black,” Eagles running back LeSean MCcoy said.

Cooper said after practice that his scuffle with Williams was “nothing,” just two competitive teammates fighting for the same football.

The Eagles open up their regular season on Monday night against the Washington Redskins.
